Implication filed December 2, 1918. Serial No. 2611,905.

and chamber for burners, and has for its object to provide anexceedingly simple and eiiective device of this character ,which may bereadily and quickly applied to burner so as to produce about said burneran air chamber to which air passes at a point below the burner tip orthe-Haine issuing therefrom when the burner is lighted so that said airwill be preheated and caused to liow directly into the vllame therebyproducing a unich larger flame and of course a much brighter lightwithout any addi- 'tional flow of gas and at thev same time thedisagreeable odor and smoke will be eliminated.

A 'furtherobject of the invention is to provide a device of thecharacter described which may be frictionally mounted upon a burner anyordinary or well known construction used for lighting purposes and whichwill so mix the necessary amount of air at the point of combustionthereby rei ducing the consumption of gas or increasing they size andbrightness ofthe llame issuing7 from the burner. y

A still further object of the invention is to provide a device of thischaracter which will cause air to be injected into a flame wherebysul'licient oxygen is supplied to create a perfect combustion so thatthe particles of unburned substances ,which will. throw oit as smokewill be consumed which will eliminate disagreeable odors and 'which willprevent soiled ceilings or wall papers.

The device is designed to be constructed of either one or two parts sothat it will be inexpensive in the cost of manufacture, .will have noparts to get out of order and which may be readily. and quickly placedin posi-` tion and adjusted to give the desired size of iiame orbright-ness of light.

lilith these ends in' view this invention consists in the details ofconstruction and combination of elements hereinafter set and usefulimprovements in combustible smokeless a1r forth and then specificallydesignated by the claims.

In order that those skilled in the art to ywhich this inventionappcrtains may Aunderstand how to make and use the same, I will describe'its construction in detail referring by numerals to the. accompanyingdraw-ings forming a part of this application, in which- Figure l, is aside elevation of my improved combustible smokeless air and gas chamberfor gas burners showing it applied to a gas burner.

Fig. 2. is a vertical sectional view thereof. the burner being inelevation.

Fig. 3, is a similar view of ag slightly ,modified Yform oli myinvention, the. same being removed from the burner.

Fig. 4, is a side elevation oit the nipple used in the constructionillustrated in Fig. 3.

Fig. 5, is a side elevation of a still further modiied form of myinvention.

Fig. (i, is a plan View oi Fig. l, and Fig. 7, is an enlarged section atthe line 7-7 of Fig. 1.

ln carrying out my invention as here cmbodied 2 represents a gas burnerof any well known construction and o1 any desirable size and shape, theone here illustrated being the same as is commonly used for suppl vinglight and this burner is provided with a slotted tip On this burner isadj'ustably and slidably mounted my improved combustible .smoke less airand gas chamber for gas burners 4 which as shown in Figs. l and 2consists of a bodyo any desirable shape,size or configuration to snuglylit about a portion of the gas burner in order that the same willlirictionally engage said gas burner so that the device may be adjustedvertically or longi-v tudinally thereon and .which will remain in itsadjusted position by the frictional conu tact 'thereof with the burner.From the body projects an enlarged portion" or bowl 6 which may be ofany desirable configuration or design and which might enhance the valueof the device from the standpoint of beauty.

Above. the bowl will `form air inlets 7 which may be produced by cuttingthe metal away to leave a number of spaced ribs 8 .with large openingtherebetween as shown in Figs. l and 2 or the metal from which thedevice is produced may be perforated as lill shown at 9 in Fig. 5 andabove these air inlets is located a head 10 which is spaced from the gasburner and its tip to produce an air chan'iber 11 and this head isprovided with an annular projection or flange 1Q formed in some suitablemanner as by producing an outwardly projecting concaveconvex ridge andthe extreme upper end of said head is flared outward as indicated at 13which becomes a guide for the flame issuing from the burner.

In Figs. 3 and 1 I have shown anotherl form of my invention in whichthe. main portion is an exact duplicate of that shown in Figs. 1 and 2,but to this latter device is added a thimble 14 which is adapted to beplaced in the outer or supporting part .flared out vard as at 16 afterthe manner of the mouth of a bell and this flared portion is adapted toapproximately lcoincide with the fiared portion 13 of the outer part ofmy device so as to support the thhnble and properly position the sameand when in use this thimble is spaced from the gas burner 2 in the samemanner as the head 10 so that an air chamber is formed about said gasburner.

In Fig. 5, the device shown is the same as that illustrated in Figs. 1and 2 with the exception that that portion thereof between the bowl Gand the head 10 is perforated as before stated to provide the necessaryair` inlets communicating with the air chamber 11,

In practice the device is placed upon a gras burner as shown in Figs, 1and 2 and the same adjusted verticallyor longitudinally of the gasburner in order that the head thereof will be in the proper positionvrelative to the burner tip 3 for supplying the necessary air andcausing the same to iiow into the flame at the point of combustion. After the proper adjustment has been obtained the/air will flow into theair inlets 7 because of the draft induced by the flame issuing from theburner and as this air flows into the air chamber 11 it will be raisedin temperature by its contact with the walls of the head 10 so that whenmixed with the fiame a necessary amount of preheated oxygen is suppliedto cause the ordinary,noncombustible materials to be consumed thereby eli mi nating' smoke and disagrceablcoders. y In actual practice itv hasbeen found that by forming a Harige or ridge 12 about the head justabove the air inlet openings much better results are obtained andpresumably this ridge acts as a baffle and produces the air eddies orcurrents which causes a greater amount of air to flow through the airinlets than would be the case if no ridge or flange were provided.

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be limited within the limitsof the appended claims without departing from the spirit of myinvention.

Having thus fully described my invention what I claim as new andpatentable is 1. In a device of the character stated a h ody adapted tofrictionally engage a gas burner, a bowl projecting therefrom, spacedribs formed integral with said bowl and forming air inlets therebetween,a head carried by said ribs of a greater diameter than the burner onwhich it is mounted thereby producing an air chamber with which the airinlets communicate, said air chamber being' opened at its upper end, theupper end of said head being flared out fard and a concave-convexannular ridge formed on the exterior of said head upon the inlet openV4ings.

Q. In a device of the character stated a body adapted tofrictioallyengage a burner. a bowl,.projectingtherefrom, spaced ribsformed integral with said bowl and forming air inlets therebetween, ahead carried by said ribs of a greater diameter than the burner on whichit is mounted thereby producing an air chamber with which the air inletscommunicate, said air chamber being opened at its upper end,v the upperend of said head. being flared outward, a concave-convex annular ridge.formed on the exterior of said head uponthe inlet openings and a thimblehaving a flared end adapted to be placed in the head and extended intothe bowl so as to be disposed across the air inlets, said thimblehaving' a flared end for positioning the same and provided withperforations to produce air inlets leading to the air chamber.

3. In a device of the character stated a body adapted to snugly t abouta gas burner, an integral bowl formed therewith, an integral perforatedportion projecting therefrom of greater diameter than the burner onwhich it is placed, an integral head formed with said perforated portionalso of greater diameter on which the device is placed to produce an airchamber, the perforations in the perforated portion .forming the airinlets to said chamber, the upper end of said head being flaredoutwardly and anl exterior annular ridge projecting from said head.

In testimony where0f, I have hereunto affixed my signature.
